: Fix typo in property name.The property name has a typo:
sceneInitilized
should besceneInitialized

`src/**/*.{ts,tsx,js}`: Review the React.js/TypeScript/JavaS...
src/**/*.{ts,tsx,js}
: Review the React.js/TypeScript/JavaScript code for best practices and potential bugs.
Ensure that the code adheres to TypeScript's typing system and modern standards.
Use the following code guide documentation in the codebase: 'docs/code-guidelines.md'.
Ensure sufficient error handling and logging is present, but note:
- We have a global error handler in place. So local
try/catch
blocks are not required unless they provide value beyond what the global error handler already covers.- Avoid flagging the absence of local error handling in cases where the global error handler suffices.
- Avoid flagging the absence of logging in cases where the global logger is already in place (graphql usage).
Inform about the recommendation of not using non-null assertion,
except on GraphQL queries where the variable is asserted non-null and followed by a
skip:
with the same variable.
Examples:
- Not Required: there's a skip
{
variables: { templateId: templateId! },
skip: !templateId,

: LGTM! Performance optimization through throttling.The timing adjustments effectively reduce event frequency:
- Mouse location updates throttled to 10fps (100ms) from ~30fps
- Full scene sync interval doubled to 10 seconds
- Scene updates throttled to 10ms intervals

: LGTM! Improved semantic naming.Renaming
socketInitialized
tosceneInitilized
better reflects that we're waiting for scene initialization, not just socket connection.src/domain/common/whiteboard/excalidraw/collab/Collab.ts (2)

: LGTM! Well-implemented throttling mechanism.The throttling implementation effectively reduces scene update frequency while maintaining data consistency through version tracking.
218-228
: LGTM! Optimized event handling.Good optimization to prevent mouse location handling until scene initialization is complete, which can improve loading times.
merged as part of release 10 |
The emission of the following events is throttled, meaning the client sends fewer events, thus less data
mouse location events throttled to 10 times per second (30 previously)
element mutation events throttled to 100 times per second (200 previously)
client will not handle mouse location events until the scene is fully initialized
